Milliohms

4,700

mΩ

4.7 Ω = 4,700 mΩ

mΩ = Ω × 1000

Ohms to Milliohms: 1 Ω equals 1000 mΩ. To convert ohms to milliohms, multiply by 1000 (mΩ = Ω × 1000). For example, 10 Ω = 10000 mΩ.

How to Convert Ohms to Milliohms

To convert from ohms to milliohms, multiply the value by 1000. The conversion is linear, meaning doubling the input doubles the output.

Conversion Formula

  • Ohms to Milliohms: mΩ = Ω × 1000
  • Milliohms to Ohms: Ω = mΩ ÷ 1000

Understanding the Units

What is an Ohm?

The ohm is the SI derived unit of electrical resistance, equal to one volt per ampere (1 Ω = 1 V/A).

Named after Georg Simon Ohm (1789–1854), German physicist who formulated Ohm's law.

Common contexts: circuit design, electronics.
